Twitter co-founder Ev Williams to step down from the company’s board

Ev Williams, a co-founder of Twitter and the social media business’s former chief executive officer, is stepping down from its board of directors effective at the end of the month, according to documents submitted to the U.S. Securities and Exchange Commission on Friday, first reported by CNBC.

“I’m very lucky to have served on the @Twitter board for 12 years (ever since there was a board),” he wrote. “It’s been overwhelmingly interesting, educational—and, at times, challenging… Thank you, @jack and @biz for starting this crazy company with me—and continuing to make it better and better. And to my fellow board members, new and old—some of the most thoughtful people I’ve ever known.”
